Trying to find beta on Mount Veniminof and have been unsuccessful. It very well may be a virgin peak. If anyone out there is interested in roping up and giving this ultra prominent active stratovolcano a shot let me know. Any info at all is appreciated ( nieghboring peaks ect...)

akanger,
You ask an interesting question. I realize this may not be much help, but here goes:
Early references (http://www.avo.alaska.edu/pdfs/cit1871_5.0.pdf) indicate that Bernard R. Hubbard (aka "the Glacier Priest") was in the area in 1930.
It would not be suprising if Hubbard made a first ascent.

If you haven't already dug through it, this list of online documents may provide some additional clues as to possible ascents, but obviously requires some digging/research. It looks like much of the stuff is geology/glaciology oriented. But then again, many geologists/glaciologists climb the mountains they study. There may be a reference in there somewhere on ascent date(s) and route(s).

Hopefully somebody out there has more specific answers.
FWIW, it's been years since I've read Hubbard's Aleutian exploration book, but I recall it was interesting reading (it seems hard to find decent early climbing/exploration books on the Aleutians that are easy to read ). Interesting read by an interesting character. Worth it if you get the chance.
Good luck!

I believe that Bernard Hubbard and R. Chisholm made the first recorded ascent in 1930. You might check out Hubbard's book, Mush, You Malamutes.
